It's a minimally invasive approach in the treatment of vascular diseases of the central nervous system. It is a medical specialty that uses radiologic images to guide catheters and other tiny instruments through blood vessels and other pathways of the body to treat a wide variety of neurological conditions that in the past required surgery.
- Stroke treatment with clot-busting drugs that go directly to the site of the blockage
- Aneurysm therapy by inserting platinum coils into the aneurysm bulge to prevent clotting and rupture
- Spinal treatments by injecting cement into a fractured vertebra in order to reinforce the bone.
With this technology, interventional neuroradiologists can see enhanced views of the brain in three dimensions.
They then snake a catheter through a major artery in the leg or arm directly to the stroke site in the brain where a clot-busting drug can be delivered in the case of an ischemic stroke. And for a hemorrhagic stroke, coils can be placed to stop the bleeding.
MERCI Clot Retriever
For stroke patients that are not candidates for the clot-busting drug t-PA, interventional neuroradiologist can use biplane angiography to guide the MERCI (Mechanical Embolus Removal in Cerebral Ischemia) Clot Retriever — a tiny corkscrew-shaped device — inside a catheter through the blood vessel to the site of the blockage where it can be used to grab the clot for removal.
The Penumbra System is available for stroke patients who are not candidates for the clot-busting drug t-PA. Interventional neuroradiologists can use biplane angiography to guide the Penumbra to a blood clot in the brain. The system removes the blockage using a microcatheter and unique separator system to restore circulation within the brain.
